Which term is commonly used for a drug that slows brain and body reactions?

• A. Stimulant
• B. Depressant
• C. Inhalant
• D. Anaphylaxis

Answer: (B)

Drugs that slow brain and body reactions are depressants. They work by dampening the activity of the central nervous system, which lowers alertness, slows reflexes, impairs coordination, and makes thinking seem sluggish. That’s why a depressant decreases response speed and can dull judgment, which is especially risky in activities that require quick reactions, like driving or operating heavy equipment. Stimulants, in contrast, do the opposite by increasing CNS activity, making you more alert and quicker to react. An inhalant refers to a broad category of substances inhaled to produce psychoactive effects and can include depressants, but the general term for a drug that slows reactions is depressant. Anaphylaxis is a severe allergic reaction, not a category of drugs affecting brain and body speed.
